Abstract: A transducer positioning apparatus includes a frame, a flexible member attached to the frame, and a guide member suspended from the frame by the flexible member. A carriage with a transducer mounted thereon is movable with respect to the guide member between multiple positions relative to the guide member. The apparatus further includes an actuator associated with the carriage. The actuator is operative to move the carriage with respect to the guide member to a selected position of the multiple positions and to move the carriage and the guide member relative to the frame to locate the transducer in a desired position. Furthermore, the flexible member is configured to allow axial movement of the guide member while inhibiting rotational movement of the guide member.

Abstract: A transducer positioning apparatus includes a frame, a first carriage movably associated with the frame and having a guide member, a second carriage that is movable with respect to the guide member between multiple positions relative to the guide member, and a transducer mounted on the second carriage. An anti-rotation member is associated with the second carriage for inhibiting rotational movement of the second carriage as the second carriage moves with respect to the guide member. The apparatus further includes an actuator associated with the second carriage. The actuator is operative to move the second carriage with respect to the guide member to a selected position of the multiple positions and to move the first carriage and the second carriage relative to the frame to locate the transducer in a desired position.

Abstract: A servo track write head writes low frequency transitions for fine transverse positioning and high frequency fields providing additional information. The servo track write head includes a first write gap with at least one gap section at a first angle relative to a tape direction. A second write gap has at least one gap section at a second angle, not equal to the first angle. The first and second write gaps write low frequency transitions in each servo frame. A third write gap writes high frequency transitions in each servo frame.

Abstract: Disclosed are compositions and methods comprising a novel mammalian gene, designated MORC, that is expressed in male germ cells. Also disclosed are polynucleotide compositions comprising a MORC gene from human and murine sources, and polypeptides encoded by these nucleic acid sequences. Methods for preparing MORC polypeptides, transformed host cells, and antibodies reactive with MORC polypeptides are also provided. In certain embodiments, the invention describes methods for diagnosing and treating infertility or testicular cancer, as well as methods for identifying MORC-related polynucleotide and polypeptide compositions.

Abstract: A multi-track read module including a hybrid thin film and mechanically closed shield includes a bottom shield layer onto which read elements are formed. A top shield is deposited over each read element. Each top shield is magnetically isolated from any other top shield and from the bottom shield layer. An insulative spacer layer is deposited between the plurality of top shields. A mechanical closure is affixed to the spacer layer.

Abstract: A magnetoresistive element for a dual element read head should exhibit uniform current density for proper biasing and Barkhausen noise limiting. Each element is a thin film MR layer normal to the magnetic media. Each element includes a front edge parallel with the magnetic media surface. A back edge, longer than the front edge, is opposite the front edge. Conductors through which current enters and exits the MR layer are adjacent to either end of the back edge.
